Given the mapping in the figure, the range set is:
{1, 2, 5, 5, 8}
{2, 3, 5}
{1, 2, 3, 4}
{2, 5, 8}.
Given the function f defined over R by f:x → 2x² - 3.
The value of f(-2) is:
-7
-11
5
-5
Given the function, f(x) = 1 - 2x. The value of f(-3) is:
7.
5.
-7.
-5.
The point (5, 4) when reflected in the line x = y. has image
(5, 5).
(-5, -3).
(2, 3).
(3, 5).
The figure shows a relation from set A to set B.
The range of the relation is:
{ (a,1), (b,1), (c,4), (d,2) }
{a, b, c, d}
{1, 2, 3, 4, 5}
{1, 2, 4}
